If you don't have a text-local.dat (and you likely don't), that means that your installation only knows about en, but you try to make it use en_DW in one of the config files.
Trying to see those files gives me 500 pages, but at a guess, one of them (I can't remember which one offhand) has either @LJ::LANGS set to qw(en_DW en) or $LJ::DEFAULT_LANG set to "en_DW" (which could happen if you leave it unset, since the default value is $LJ::LANGS[0]. If that's the problem, just remove en_DW from @LJ::LANGS and remove any setting for $LJ::DEFAULT_LANG. That should fix it.
(Note: those may be present as @LANGS and $DEFAULT_LANG in the files)
If that still doesn't work, comment with the contents of the config files. (Suitably sanitized - we don't need to know the password for your MySQL database, or any other sensitive information)
